The FT-Raman and FT-IR spectroscopic analysis of 2'-nitroacetophenone (2NAP) were performed. The vibrational spectra of 2NAP was found by applying the Density Functional Theory Calculations based on Beck3-lee-yang-parr (B3LYP) level with the use of the standard 6-31G*/6-311+G** basis set. The vibrational wave number for the optimized geometry was calculated at the same level of theory. The computed values of frequencies are scaled using an appropriate scale factor to give up the excellent unity…

3. Results and discussion 3.1. XRD analysis The X-ray diffraction (XRD) pattern of Sn-substituted Ni-Zn ferrites with the chemical composition of Ni0.6-x/2Zn0.4-x/2SnxFe2O4 (NZSFO) are shown in Fig. 1. The XRD spectra were indexed and fcc cubic phase was identified. The structural parameters are calculated from the XRD data and have been discussed in Ali et al [6]. The lattice constants are calculated from the XRD data and represented in Table 1. The distances between the magnetic ions at…

Keep batteries stored in LiPo-safe bags. How will you flow between the activities? Start with a whole group safety briefing and watch the Droneology videos all together on the projector. Break into teams to build, then come back together in P2 to talk through flight dynamics and essential terminology. Split to individual computers to take the Lesson 2 Quiz in C1. Come back together to watch the next batch of videos in C2 and end with a review of safety procedures in the DP. What does FPV stand…

Conclusion Through burning varied solutions in a flame the information that is found becomes very useful. While burning any solution in a flame it produces a flame on the visible line spectrum. This flame color allows for a brief understanding of the energy the solutions possess. The least energy in the visible light spectrum is the color red and the most energy is violet. According to the data found in the experiment we come to the conclusion that the least energy is Lithium Nitrate due to…

INTRODUCTION Millimeter wave therapy is the exposure to a frequency that ranges from 30-300 GHz. This frequency is located in the radio frequency region of the electromagnetic spectrum. Due to the extremely small wavelength the frequency will only penetrate up to 2 mm of skin. In therapy the frequency is irradiated on certain parts of the tissue, depending on the specific treatment and energy it is deposited in the skin causing a variety of beneficial reactions. In the Former Soviet Union (FSU)…

The Life Of Richard Pryor Who was Richard Pryor, some people might ask? Well he is an African American Actor/ Comedian. One of his most famous quotes is ‘If I thought about it, I could be bitter, but I don't feel like being bitter. Being bitter makes you immobile, and there's too much that I still want to do. Richard Pryor is known for his colorful language during his live comedy shows , and he is highly influential , and always controversial towards African Americans. He has also been…

Discussion and Scientific Explanations Colors help most people describe what different objects look like. When white light hits an object, in most cases, the object will absorb all of the wavelengths, except for one group. This group of wavelengths is then reflected off of the objects. The cones and rods in our eyes will then pick up this wavelengths and then the brain sees them as “color”. The reason that solutions have colors is because electrons in the chemical’s 4d orbital are jumping…

The purpose of this spectroscopy, atomic spectra, and light lab was to further your understanding of how different gases are given specific wavelengths based on the variety of color that their light gives off. (Grossie, 285). Every ion gives off a different light configuration based on the amount of energy they hold. (Grossie, 285). A spectroscope is used to break down the light given off by the gas into different colored lines in different areas on the scope. The measure of these lines is what…

UVB’s 1. The sun shines on the skin. 2. The UVB light interfaces with a form of cholesterol in the skin called 97-dehydrocholesterol. 3. This is synthesized into pre-vitamin D3, which is immediately converted into vitamin D3. 30 minutes of midday sun in a bathing suit, and you’ve absorbed up to 20,000 IU of vitamin D. Whether you spend half an hour in the midday sun or take 2 10,000 IU of vitamin D3 in tablets, it’s then transported to the liver where it’s turned into D25 for storage. These…

4. Why PdO/TiON NP powders are chosen as photocatalyst? There are many reasons why PdO/TiON NP powders are chosen as a photocatalyst for MTBE mineralization under visible light. These reasons are listed and discussed as follows: 1- The synergistic effect. 2- The ease of synthesis. 3- The memory effect. 4.1 The synergistic effect Nowadays, modified TiO2 by metal and nitrogen is considered as one of the most promising TiO2 based materials for photocatalytic applications, which is able to…
